SASH-CORD GUIDE.

SPECIFICATION forming part of Letters Patent No. 612,684, dated October 18, 1898.

Application filed May 15,

To aZZ whom it may concern:

Be it known that I, J osEPH F. THOMPSON, of Marietta, in the county of WVashington and State of Ohio, have invented certain new and useful Improvements in Sash-VVeight-Pulley Supports; and I hereby do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sash-weight-pulley supports; and it consists, essentially,of a device of this character formed from a single piece of sheet metal and by the details of construction and arrangement of the several parts of which it is made to serve not only as a guide and wear plate, but is also adapted to be readily set up in operative position and held secure by the insertion of a single fastening, as hereinafter described and claimed.

The object of the present invention is to simplify devices of the character specified to such an extent as to make their cost of manuture materially reduced without detracting from their efficiency as supports.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a windowframe, showing the improved sash-weightpulley support applied thereto and broken away in parts to illustrate the mode of attachment. Fig. 2 is a detail perspective view of the support disconnected. Fig. 3 is a detail perspective view of the support, looking to ward the rear thereof.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates a window-frame supplied with a head 2, an inside stop 3, a parting stop or bead 4t, and an outside stop 5, together with other useful accessories in such form of devices. In the grooves 6, formed between the inside stop 3, outside stop 5, and the parting-stop 4:, the improved sash-weightpulley support is adapted to be mounted, and consists of a sheet-metal plate of a non-corrosive nature struck into form to provide rearwardly-extending wings 7 of circular contour and embracing the sash weight pulley 8, which has free rotation between the said 1897. Serial No. 636,753. (No model.)

wings on a pivot-pin 0, headed over on the outer sides of the said wings. The said wings extend backwardly in parallel planes and communicate with a front opening formed by cutting a slot 10 primarily in the formation of the support. Upon opposite sides of the said opening are right-angularly-bentflanges 11, while above and below are extensions 12 and 13, continuous with the wings 7. The usual opening 14 is formed in the frame to receive the sash-weight pulley, and communicating therewith are opposite slits 15 at the bottom, through which the continued parts of the wings communicating with the ex tension at the lower end pass, and this part of the support is then secured on the outer side or exposed surface of the groove 6, in which itis mounted, bya single screw or analogous device 16. The upper extension closes the usual opening let above the opening 10 in the support and projects upwardly under the head 2, to thereby securely hold the support at this point, while the flanges 11 also provide auxiliaries in retaining the support in position and prevent inward depression or movement thereof. The sash-weight pulley S of course projects slightly through the opening formed by the slot 10, as in the ordinary construction and arrangement of such devices, and sufficient space is left for the free passage of the sash-weight cord.

The support is entirely struck up from a single piece of sheet metal, thereby reducing the cost to a minimum and also facilitatingthe positioning of such devices through the construction and arrangement of its parts heretofore specified.

Having thus described the invention, what is claimed as new is- As an improved article of manufacture, a support for a sash-weight pulley consisting of a sheet-metal plate having a central slot cut longitudinally thereof with opposite end transverse slits to provide central flanges on opposite sides at right angles in transverse 5 box-like extensions above and below the said flanges, the said wings forming a pivotal support for the pulley, the upper extension there of being adapted to engage the frame-head and the lower extension having a perforation for the reception of a fastening device, Whereby said support is adapted to be securely held in place by a single fastening device, substantially as described.

I11 testimony whereof I have signed this specification in the presence of two subscrib- IO ing witnesses.
